I have a Shapefile containing point data that has three variables (i.e. name, width, height). I ingested it as a Feature Collection in Google Earth Engine (GEE). I want to make rectangles of varying dimensions using the 'width' and 'height' data in GEE. I do not know how to start doing this. In GEE, the closest thing I can do is to create square buffers around a point using .buffer() and .bounds() as I show in the sample code below but that is not what I want.

Can anyone advise on how I can code to create geometries of varying dimensions from point data in GEE? I have made this GEE asset publicly available for anyone to use.

This is the attribute table of the ee.FeatureCollection.

Here is the sample code I mentioned that creates a fixed distance square buffer around each point. I am not sure if this can be modified to create rectangles of varying widths and heights according to the values in the attribute table.

//  Load point data
var points = ee.FeatureCollection('users/earthorbgis/GEE_help/gee_point_sample');

//  Buffer points to 500 x 500 m squares
var buffer_interval01_MMR = points.map(function(f) {
  return f.buffer(250).bounds(); 
});

//  Create custom rectangles using point data columns Width and Height
//  Unsure how to start ...

You can achieve the result using the same .bounds() and .buffer() method. Follow these steps:

  1. Create buffers of height/2 and width/2
  2. retrieve min-max coordinates of the buffers and save it as separate properties in the points FeatureCollection
  3. Use the saved coordinates to draw rectangles around each point

  • I used your code on a small subset of my data. I created the rectangles and exported them out of GEE as Shapefiles. I inspected them in QGIS and was very happy to see that the solution works exactly as desired. Thank you @kkrao for the crisp, efficient and creative solution! Feb 23 at 7:48
  • The current code results in ee.FeatureCollection as intended. However, it does not preserve the initial information in the 'points' input layer. How would I tweak the code such that I would preserve information per feature on the column 'Name'? I would like to avoid a spatial join because there may be overlapping rectangles, and would like to just preserve the Name information in the output Feature Collection. Aug 12 at 12:42
  • Since my previous comment is a different question, I will add a new post linking this one. Aug 12 at 14:17
